Dear student,

First of all, congrats for your fabulous performance in JEE Main.

As you may know, the cutoff depends on various factors and varies for different courses and different institutes. Since, you haven't provided your home state so it won't be possible for me to tell the NITs. But, you can check the previous year cutoffs to get an idea regarding different NITs here and I am also attaching the link to a college predictor where you can check your chances for different colleges .
